Hello everyone! As people become more demanding about air quality, air purification systems have grown increasingly complex and precise. Pre-filters serve as the first line of defense, removing larger dust particles, while high-efficiency filters focus on eliminating ultra-fine pollutants to provide us with the purest air possible.
Positioned between these two, medium efficiency filters play a crucial role, acting as a bridge in the air purification process. They receive the air treated by pre-filters, further removing medium to small-sized dust particles and some harmful gases, providing high-quality air for high-efficiency filters. This significantly enhances the overall performance and effectiveness of the entire air purification system.
A Variety of Medium Efficiency Filter Products
Medium Efficiency Pocket Filter
The medium efficiency pocket filter is reusable, has low resistance, and handles large air volumes, making it a common choice for mid-level filtration in air conditioning systems.
The frame is made of aluminum alloy or galvanized steel, which provides a solid “framework.” The filter material consists of a new composite non-woven fabric made from a blend of [list some main fiber components]. These fibers are woven together through a special process, creating a porous structure that allows air to pass through freely, ensuring good breathability. At the same time, the densely interwoven fibers effectively capture dust particles, ensuring excellent filtration performance. It’s like a carefully woven filter net that allows air to flow smoothly while blocking impurities.
The filters come in a variety of colors, such as F5 (white) 45% (light yellow), F6 (green) 65% (orange), F7 (pink) 85% (purple), F8 (light yellow) 95% (dark yellow), with different colors representing different filtration efficiency levels, making it easy for users to choose based on their needs. The sealing strip is made of ethyl acetate, effectively sealing the filter to prevent air leakage, like a “seal lock.” It can withstand a maximum temperature and humidity of 80°C and 80%, making it suitable for most air conditioning systems in standard environments.
Medium Efficiency Pleated Filter
The medium efficiency pleated filter takes up little space, offers high efficiency, and has a large dust-holding capacity, mainly used in ventilation systems.
The frame can be made from aluminum profiles, aluminum plates, galvanized iron, stainless steel, or paper, offering various “shell options.” The filter material is made from synthetic fiber non-woven fabric, which has excellent filtration performance and mechanical strength, acting like a durable “filter cloth.” The sealing adhesive is a universal adhesive that effectively seals the filter to prevent air leakage, providing it with a “sealing layer.”
Its filtration efficiency ranges from F5 (45%), F6 (65%), F7 (85%), F8 (95%), and F9 (98%), allowing users to select the appropriate level based on their requirements. It can withstand a maximum temperature of 80°C, and when using paper frames, the maximum humidity is 80%, while for other frames, it is 100%. The aluminum profile frame can be selected in thicknesses of 46mm or 69mm.
Meeting Specific Environmental Needs with Medium Efficiency Filters
Applications in the Electronics and Pharmaceutical Industries
In the electronics and pharmaceutical industries, air quality requirements are extremely stringent. For example, in chip manufacturing, the particle size in the air must be smaller than 0.5 microns, and the number of dust particles per cubic meter of air must not exceed 3,500 particles. In the pharmaceutical industry, the microbial content in the air must be kept very low, with bacteria and virus counts controlled to fewer than 5 particles per cubic meter.
Medium efficiency filters, with their excellent filtration performance, can reduce dust and microbial content in the air to meet industry standards. For instance, in chip manufacturing, medium efficiency filters can filter out dust particles larger than 0.5 microns, reducing the particle count to fewer than 3,500 particles per cubic meter to meet cleanliness requirements. In pharmaceutical workshops, medium efficiency filters can capture most bacteria and viruses, ensuring the air meets the hygienic standards required for drug production.
Performance in High-Temperature Environments
Some medium efficiency filters can operate effectively in high-temperature environments. For example, heat-resistant medium efficiency filters can meet special requirements, ensuring effective air purification.
These filters are suitable for applications in high-temperature environments such as ultra-clean ovens, high-temperature purification equipment, and tunnel furnaces, providing mid-level filtration or terminal filtration for general air purification.
